日本語

本論文は、EU排出権取引制度の道路交通・建物への拡大(ETS2)が脆弱な世帯に及ぼす社会的影響を分析する概念枠組みを提示。ブルガリアを事例に、経済的脆弱性、空間的脆弱性、移動依存度、インフラ脆弱性、気候政策への曝露、社会的脆弱性の6次元を特定し、低所得・農村世帯への悪化リスクを指摘。

English

This paper develops a conceptual framework to analyze transport poverty under the EU ETS2 expansion, identifying six dimensions (economic, spatial, mobility dependency, infrastructure, climate-policy exposure, social). Using Bulgaria as a critical case, it shows how carbon pricing may exacerbate inequalities without compensatory policies.

日本のGX文脈において

日本でもカーボンプライシング(GX-ETS)導入が議論されており、交通弱者の保護や地域間格差への配慮は重要な政策課題。本枠組みは日本での政策設計にも示唆を与える。

In the global GX context

ETS2 represents a landmark EU carbon pricing policy. This paper provides a structured lens for assessing its social equity impacts, relevant to global debates on carbon pricing design and just transition.

👥 読者別の含意

🔬研究者:Provides an integrated conceptual framework for studying transport poverty and carbon pricing interactions.

🏛政策担当者:Offers analytical dimensions and policy recommendations for designing compensatory measures to avoid regressive impacts of carbon pricing.

📄 Abstract(原文)

The expansion of the European Union Emissions Trading System to road transport and buildings (ETS2) raises significant concerns regarding the distributive social impacts of carbon pricing on vulnerable households, particularly in regions characterized by high car dependency, limited public transport accessibility, and pronounced territorial inequalities. This paper aims to develop an integrated conceptual framework for analyzing transport poverty in the context of ETS2 and the just climate transition. The study adopts a conceptual–analytical approach based on a structured literature review of peer-reviewed publications and EU policy documents, combined with a qualitative policy analysis focused on Bulgaria as a critical case. The paper identifies six interacting analytical dimensions of transport poverty—economic vulnerability, spatial vulnerability, mobility dependency, infrastructure vulnerability, climate-policy exposure, and social vulnerability—and maps the causal pathways through which carbon pricing mechanisms may intensify mobility deprivation, particularly among low-income, rural, and forced-car-ownership households. The analysis demonstrates that ETS2 may exacerbate existing socio-spatial inequalities unless accompanied by well-designed compensatory, accessibility-oriented, and territorially sensitive policy measures. The Bulgarian case illustrates the specific structural risk factors prevalent in Central and Eastern European countries. The paper contributes to the emerging academic literature on transport poverty by positioning it as a critical dimension of the just climate transition and by providing a conceptual foundation for future empirical research within the ACTETS2 project framework.
